His early writing is gaudy Gothic pastiche, but in his mature Cthulhu tales, Lovecraft adopts a pseudodocumentary style that utilizes the language of journalism, scholarship, and science to construct a realistic and measured prose voice which then explodes into feverish, adjectival horror.

Whereas Howard's usual style tends to neither add or subtract from a film, that actually serves the film well because when it's not a talking-head pseudodocumentary or look behind the scenes, it is essentially a verbal duel.
